I have a 1988 YJ. I got a quote of $900.00 for parts and labor ( new pressure plate, clutch disk, slave cylinder, pilot bearing) from one shop. Another shop qouted me a labor only rate of $600.00 if I provided all of the parts.
Preen is a pre-emergent weed prevention product. It prevents weed seeds from germinating instead of killing existing mature weeds. Preen works on a wide variety of annual weeds, but it won't have an effect on perennial weeds because they already have established roots.
Products. The label on Preen Lawn Weed Control lists 200 weeds that it claims to kill, including chickweed, dandelions, and thistles. Preen Crabgrass Control prevents crabgrass and other annual grass seeds from germinating for up to four months. It also kills crabgrass seedlings up to four weeks after germination.
